Space Storms Pose Threat to Train Signal Systems, Risking Serious Accidents
Space weather, particularly solar storms, poses a significant risk to train signal systems, potentially leading to serious accidents. According to Cameron Patterson from Lancaster University, solar storms can disrupt electrical systems on the ground, including those used in railway signaling. These disruptions can cause signals to change unexpectedly, such as turning a red signal green, which could result in deadly train crashes. The sun emits charged particles that can affect Earth's magnetic field, inducing currents in railway tracks and affecting signaling systems. While the risk is low, with significant solar storms occurring approximately once every 30 years, the potential consequences are severe.
